 desc = "The remote host is missing an update to dnsmasq
announced via advisory USN-827-1.

Details follow:

IvAin Arce, Pablo HernAin Jorge, Alejandro Pablo Rodriguez, MartA­n Coco,
Alberto SoliAto Testa and Pablo Annetta discovered that Dnsmasq did not
properly validate its input when processing TFTP requests for files with
long names. A remote attacker could cause a denial of service or execute
arbitrary code with user privileges. Dnsmasq runs as the 'dnsmasq' user by
default on Ubuntu. (CVE-2009-2957)

Steve Grubb discovered that Dnsmasq could be made to dereference a NULL
pointer when processing certain TFTP requests. A remote attacker could
cause a denial of service by sending a crafted TFTP request.
(CVE-2009-2958)

Solution:
The problem can be corrected by upgrading your system to the
following package versions:

Ubuntu 8.04 LTS:
  dnsmasq-base                    2.41-2ubuntu2.2

Ubuntu 8.10:
  dnsmasq-base                    2.45-1ubuntu1.1

Ubuntu 9.04:
  dnsmasq-base                    2.47-3ubuntu0.1

In general, a standard system upgrade is sufficient to effect the
necessary changes.
